Title: David John Rickeard: Innovator in Fuel Composition

Introduction

David John Rickeard is a notable inventor based in Didcot, GB. He has made significant contributions to the field of fuel composition, holding a total of 3 patents. His work focuses on enhancing the properties of diesel fuels, particularly in terms of lubricity and antiwear characteristics.

Latest Patents

One of Rickeard's latest inventions is a fuel composition that has a sulphur content of ≤50 ppm by weight. This composition includes ≥50 ppm by weight of at least one fused polycyclic aromatic compound, which contains at least one hetero-atom selected from oxygen and nitrogen. These compounds are designed to improve the antiwear and lubricity properties of low sulphur fuels, especially diesel fuels, compared to the same fuel without these compounds.

Another significant patent relates to a diesel fuel composition that boasts enhanced lubricity. This composition consists of a major amount of diesel fuel blended with a minor amount of a nitrogen-rich fraction. The nitrogen-rich fraction is derived from either a solvent extract of a solid or semi-solid natural fossil or a refinery process stream. The nitrogen content in this fraction is at least 1000 ppm by weight, and it can be integrated into existing refinery processes without substantial cost increases.
